i `This invention relates to improvements lin automobile bodies of the inclosed type.. The object is to provi-de means in the front part Lof inclosed automobile bodies whereby i3 what is known as the blind spot .at ,each front corner .of-the body is reduced to a minimum, such blind spots being brought about bythe more or lessbulky arrangement-of corner postsand the parts associated therewith 10 to :be found inthe average `,automobile and which ordinarily becomes amenace ,in .con-

` gested traffic, or'while driving yat nizghtand f in rainy weather. v Other objects of the present invention also 115 include the .provision lof a downwardly and forwardly'inclined windshield which is much desired for the reason that such shields do not .reflect the glare of headlights of cars ape,

preaching from the rear as well 1 as yromfthe im sides,- tbus removinganothermenace to driving, `and by the provision .of lsuch ay windshield, the corner postsof theibody, as well as the front `wall offthe window opening in the front doorsare necessarily .ormedina -and said vfront wall maybe located closer tothe front edge of the door than usual and suitably rounded soasvto offer,'in combination withthecorner post, the least possible obstruction to the line 99 of visionl of the driver of the car.v

By the provision o the extremely narrow com ination at the front corners ofthe body and the same being arranged at an\incline,.it becomes necessary to utilize a peculiarly shapedwindow to open and close the corresponding shape of the Window openingin. the front doors:and the invention further Contemplates a novel form'of plate glass window 'adapted to be raised and lowered along a-patli of movement substantially parallel to the aforesaid inclination of the partsand also means to guide the same'and to prevent rattling thereof, the means for actuating the window being hidden 4from view in the struc ture of the front doors, and readily operable from the front seat of the automobile. f

Referring tothe drawings, thereis shown ap'ortion of an automobilefbody" ofthe inclosed7 type, 'in whic'hthereis lmounted the frontdoorL-which may be of'an'y of the well# known constructions of eitherthe all-metal or i combination `form. vThe door is carried by a surrounding Vframe 2, said frame being` indi-y cated in solid section lining in Figures 1 and 2, to avoid confusion ldue to the s'mall scale on which they are drawn, though the preferableform of the framing is as lshown in Figi ure'7V of the drawings, wherein suitable sheet metal is stampedr or otherwise formed 'into shape to provide the necessary strength and lightness.

`=The upperf portionV lofV they front edge of the-door'is inclined rearwardlyv as indicated at 2a clined` front` corner v.post 3 of' the automo- `be hingedlat its Vrear edge if desired.

. lthe side of the usual visorr,

bile body'and said door is hingedto the body by lflower, intermediate and upper..

hingesl 4 in the usual manner, the said upper hinge being joined to the door by an armr4a, which permits. said hinge to be locatedron which in this in Stance is preferably formed of 'metaly heavy enough to withstand thestrain of assisting in supporting the door whe'nopen.'v The arm 4a may be set' into a' suitable lindentation formed in the siderofthe visor, so that all the axes ofthe hinges may be in theproper alinement'with each other; the door,"however, may

' 1The upper `portion of the door, opposite the inclined portion thereof is provided with the usual window opening 6, the front wall 6a of which is Vlocated closer to the adjacent edge 'of the door than usual, and is inclinedl tocorrespond with the inclination thereof so `that,by.the provision of thisnarrow portion,

1n :conjunction with the aforesaid narrow g `cornerpost,'thevobstruction to the vision oi lthe driver, and known as the #blind spot `is reduced toa minimum.

* .,Awindow 7 consisting preferably oifa single sheetiofheavy plate glassis, located in the usualjchamber formed betweenI the inner and outer walls of the door, and is adaptedlto be moved upwardly ,into closing relation to the windowopening and downwardly to open the 'same,"w1thout leaving any appreciable V.for it in order to to accord w'ith'the'V rearwardly in,

kfront and rearvedges corresponds substantially withthe inclination of the said corner posts though slightly more nearly vertical will. be seen, by reference to Figures l'l and 2, that'owing -to the above substantial .narrowingiof the blndrSpOJ-Afand the Vslant vofthe window opening being so close to the edge of the door, there is insuicient room,

when'the window-is lowered, as in Figurey l, l

to permit said windowA to be :moved up and down in a p'ath'exactly parallel with theslope of the'corner posts, as the lower front end of the window would strike the vertical Afront Vedgeof thedoor frame at the 'lower portion thereof, and prevent the complete opening of,

the window. rFor this reason, the window .is

causedto slide up and down, by means to'be described, in a path abouthalt way between y the vertical andthe angle of the corner posts ypermit the completefclosing of'V v opening when the window iselethe window vated, and to preventany gap between the side edges of the window glass and the edges of the window opening whenntheY `glass is only partly elevated. n

-' The front edge 8 of the glass plate is bevlelled back at its upper end, as shown at 10,

to'contact, when fully elevated, with a padded stop 11 located in the upper front corner of the door casing and in like manner the lower front corner ofv said plate is also bevelled at l2 to contact, when fully lowered, with a similar padded'stop lsecured to thelower verframe` The rear, upper corner of thefwin dow is also bevelled at 14;y for similar Contact withthe padded vstopl located `in the rear upper corner of the door frame, and is adaptedto functionat the. Vsame time as the stop ll when the window is raised. This bevelling of the corners of 'the window glass permits thereduction of the fore and aft'dimension of the door posts above the window opening and vminimizes theffobstruction to vision causedby the front door post and the adja-v cent windshieldpillar. 1

`In addition to the lower front stop 13, the 4downward movement of the window ,is

tical portion of the front wall of the door y checked by apair of spaced bottom supports order to positively guide 'the movements of thefwindfow pane `in the path .of movement described, tracks 18 vare Aemployed the ychamber in the door, said tracks consisting of 'suitable metal ,strips haviny attaching brackets 19 .for 'the reception' o fastening screws which lpreferably secure the 'tracks to the .inner 'faces of the front and rear 'walls of the door. At spaced intervals, the 'tracks are provided with ltransversely spaced ears 2O between which there are mounted rollers 21 on ypins 22, there being openings 23 formed in the traclrscto allow the roller to project slightly through the siamo .to contact with .the edges ofthe win- It :has been found that the above mentioned marginal padding 17 around the 'window .opening constitutes sufficient means to prevent :any later-al movement of the window pane when the llatter iselevated, but when the same is lowered intothespace below the window opening, such movement is prevented by side flanges portions of the tracks. y

Any Lsuitable and convenient means may be 'emplio ed for raising andi'lowering'gthe window, ut I prefer yto employ the means shown in the drawings, thoughv no specific claim :is made to the same herein.

The lower edge'of the window is provided a flanged met-al strip 25 secured to the same in 'any desired 'manner and extending across the major .portion o f the bottom edge, so .as to erertsa uniform lift to 'and prevent breakage of the otherwise unsupported `plate of glass. i

The strip 125 is provided at its center with l 'a pai-r of spaced, depending ears @6to Vwhich is attached the upper end of'a toggle lever element .27, the 'lower -end v'of which is similarly connected'between vears 28 upstanding from a :supporting bracket 29 secured to the fbottom frame member of the door. f

' The toggle lever element is adapted to ybe actuated in the usual manner for raising and lowering the window Iby a link 30 connected at its lower end to one of :the lower pivotall points of the crossed toggle levers, and said link `extends :upwardly and is terminally connected to a 'cranlr arm 3l located between the inner face ofthe inner wall of-the door Vand the window. f The crank arm 31 is fixed to Ya rotatable shaft 32 mountedhorizontally in the inner wall of the door and having a suitable actuating handle 33 at the inner face of the door and within easy reach of the occupantsuof the front seat-of theautomobile. The handle 33 is pre-ferably'provided with a 'suitable pawlv 4connection with a toothed, arcuate rack 34 secured to the inner face `of .the dooran'd adapt-ed to positively lock the Window xin its upper or lowermost position or in various intermediate positions. Y

'By the arrangement of lthe toggle levers',

24 'formed on the lower the window may be caused to be fully Yopened or closed by substantiallyja `half turn of the crank, the power being increased vsufficiently to allow =of such action to be easily and 'quickly accomplished, and the window is caused to follow the said inclined path of movement to tightly close and seal the window with themaximurn `amount of window opening in the upper .portion yof the .door and the minimum zamount of obstruction to the vision of the driver by the so-called bl-ind' spot which has, by the above arrangement lof parts, lbeen greatly reduced -in area.

f One or more of the crossed toggle levers are preferably provided with swivelled eyes 3'5`located at vtheir points yof .crossing and said eyes are adapted-to slide on a rod V'36 arranged `at the same angle Vas the path of movement of the window and secured at its upper and lower Vends to the inner face of the outer wall of the door, as indicated at l37. This rod, with which the'toggles are` thus' slidably connected, elfectually prevents `rattling of the toggles and serves to further eliminatenoises. I

The front corner posts 3 rare-providedwith rearwardly-extending abutment 'flanges 38 located at their inner edges for the door to fit against and the width ofY said `corner posts, taken transversely of the automobile, has been greatly reduced so asto allow of' a larger windshield area and reducethe blind spot in this direction, as indicated-by thevdotted lines A representing the lines of vision-'of the drivenas in Figure 7 of the drawings. A*This reduction transversely ofthe automobile necessitates a 'like reduction in the. transverse thickness of the upper portion of the door., said point of reduction being' indicatedv at la inFigure 3, 'so that the upper portion 1b of vthe door is considerably thinner than the lower portion thereof, and the point -la is preferably `located at the rlower line ofthe window opening, and is in the'form 0f a ledge or 'sill to conveniently rest the arm of .the driver.

In the preferred form of `front corner post 3, as indicated at Figure 7, there is :an'intermediate, vertical wall 'or web 39 formed therein, and the inner bevelled wall 4() is provided with a continuous, vertical slot'in which is suitably held felt padding 41 for` a slidable windshield l2 to move in at the angle of inclination of the front corner posts.

rThe outer wall 43 of the narrow inclined l portion of the door in advanceof the window opening is curved on as wide a radius as possible to reduce the blind spot, as indicated inv Figure 7, it being advisable to employ such arcuate form forstreng'th vand attractiveness in appearance. v

A slightly mo'diiied formof front corner post is shown in Figure 8 ofthe drawings wherein the inner, bevelled wall 44 of the ,same is1not;s`lotted,:as in Figure 7, and a forwardly-extending `iange is provided, the

same having a felt facing 46 secured thereto, and a similar felt'facin'g 46a is secured tothe frontface ofthe same post. A hinged wind, shield47, secured in a, felt seat 48,' mounted in:V a groove49` ofraiwindshield frame 50, is adapted to be Aswung upwardly and downwardlyv on overhead hinges (not shown) vin a -well-known manner and to rest, when closed down, against the said felt strip 46avfor the exclusion of air and moisture, the'said' frame f 50 havingan overhanging'flange .5l to surfand the reduction round the facing 46 to aid in :said exclusion. From the foregoing itis thought a full and lcomplete understanding of the invention and Y the' merits thereof may bevobtained, and'it will be seen that by'reason'of the aforesaid transverse reduction in the width of the door to a minimumof that porin advance Vof the window taken longitudinally 'of the auto- '.that v the so-called blind spot. has beengreatly reduced, and that cient-means has been provided jfor causing the window to yfully and completely closeand seal the Awindow opening,or to open or partially'open the same Without uncovering any tion of Vthe, door gap between any but thetopjedge of thewin'- dow glass and the top edge of the window opening,.by moving said window in an angular directionwi'n'such necessarily confined space ,withinthe chamber of the door.V .What is claimedV is: 1;v Anxinclosed automobile body having rearwardly inclined front corner posts and wind shield, front doors havingv Window openings, the, front edges of said openings corresponding to the inclinationY ofthe c orner posts, -a' unitary window pane mounted Within each door and having a front edge inclined from vtop to bottomrthereof, and' means Vfor sliding the window' upwardly and downwardly in apathrcorresponding substantially to said inclination.
